Impact resistance Zoomlion ZR280 Rotary Drilling Rig

Double large triangular back variable amplitude mast

The deformation of the drilling mast in hard rock is minimal, and the verticality of the borehole is high; The mast can be placed backwards, and there is no need to dismantle the mast during transfer, resulting in high transfer efficiency

Three speed reduction power head

Low speed and high torque, strong rock penetration ability in moderately and weakly weathered rock layers, and can be used with a down the hole hammer to drive hard rock piles

Mid mounted single row rope main winch

Single layer drum, low wear and longer service life of steel wire rope, lifting speed of 72m/min, high soil lifting efficiency

Strengthen chassis+large slewing support

Low center of gravity design, strong stability for heavy load and steep slope construction, traction force of 557kN

Intelligent electronic control

360 ° panoramic monitoring, remote viewing of working conditions/fuel consumption/faults through mobile app; Multi speed power adaptive soil layer, fuel-efficient and efficient
